Has description A stand modelling system “STANDPAK” has been used by the New Zealand forest industry over two decades (1988 – 2008). It was developed and supported by researchers at Scion (New Zealand Forest Research Institute Ltd) and has been through the full cycle of development, use and redundancy. It is to be replaced by a new generation DSS called Forecaster.

The STANDPAK system was empirical, modular and deterministic. It primarily provided a mechanism for the integration of numerous research results and gave managers and investors a method of objectively evaluating alternative management regimes for plantations of radiata pine. The system was deployed on early personal computers as a DOS application, ie was not adapted to run as a WINDOWS application. STANDPAK predicted the growth of stands (allowing for the effects of site, genetic improvement and stand management), calculates diameter distributions at harvest and produces stand volumes by log size and quality. Potential sawlog values may then be predicted under a range of processing and pricing scenarios. The effects of trees on pasture and hence livestock production in agroforestry situations was also predicted.

A second phase of development has been in the area of wood quality and carbon sequestration. The ability to predict the quantity of juvenile wood and number of rings per log have been added to assist with concerns of wood quality associated with shorter rotations. A algorithm has been added that predicts the allocation of stand biomass to roots, stems, branchs, and needles, this allows the calculation of the amount of carbon sequestered as the stand grows while accounting for the impact pruning, thinning, mortality, harvesting and decay of tree components.
